Detailed explanation of the working principle of the switching power supply

      Compared with traditional power supplies, switching power supplies have the characteristics of low power consumption, high efficiency, small size, light weight, wide voltage regulation range, etc., and are widely used in computers and peripheral equipment, communications, automatic control, household appliances and other fields.

      However, the outstanding disadvantage of the switching power supply is that it generates strong electromagnetic interference. The interference signal has a wide frequency range and a certain amplitude. The conduction and radiation will pollute the electromagnetic environment and cause interference to the communication equipment and electronic products. If not handled properly, the switching power supply itself becomes a source of interference.

      So if you find a switching power supply that is suitable for audio use in the market, it is not cheap.

      Because of these shortcomings, switching power supplies are generally not used in professional audio applications.

      The traditional transformer power supply has the disadvantages of heavy volume and low efficiency. However, in order to pursue profits, manufacturers on the market use inferior selenium steel sheets or fakes, which leads to overheating of the transformer and lower efficiency. Therefore, when purchasing power, try to Use a good quality transformer power supply.
